Prairie Spirit Trail State Park is a rail trail that is a Kansas State Park.
The trail is built on the former right of way of the Leavenworth, Lawrence and Galveston Railroad from Ottawa, Kansas, to Iola, Kansas. The trail runs 50 miles from its northern terminus at Ottawa, Kansas to its southern terminus at Iola, Kansas.
The trail is open for use by hikers, joggers, and bicyclists year-round, from sunrise to sunset. This trail is paved with a hard-packed limestone screening outside of the city limits of Ottawa, Garnett, and Iola. Inside Ottawa, Garnett, and Iola, the trail is paved with asphalt. A Kansas State Park vehicle permit is not required, but a separate trail permit (daily/annual) must be purchased for those using the trail outside the city limits of Ottawa, Garnett, and Iola.
During flooding in June 2007, a section of the bridge carrying the trail over Pottawatomie Creek north of Garnett washed out. The bridge has since been replaced.
